[Bug 1261338] [NEW] lxc-stop and even lxc-stop -k can hang

[Vincent Ladeuil]

Public bug reported:

and even 'lxc-stop -k -t <timeout>' can hang :-/

The context is an automated test run with otto using a lxc-container
trigerring a kernel crash on the host.

The host is still alive and so is the container but trying to implement
a catch-all to stop a container left running is blocked because there is
no way in this particular case to stop the container.

The only alternative so far is to reboot the host :-/

=qa-intel-4000/951/console is one occurrence where the kernel crashed
and 'lxc-stop -k -t 120 -n trusty-i386-20131216-0008' hanged requiring
the job to be aborted.
